At about $750 per year in fuel (EPA estimate, 15,000 mi/yr), fuel is a major part of the cost of owning the 2018 smart fortwo electric drive convertible. Over five years that is roughly $3,750 at today's prices — before insurance, maintenance, and depreciation.
How to read these numbers
EPA figures come from standardized laboratory test cycles and are the same estimates shown on the vehicle's window sticker. Your real-world mileage depends on driving style, conditions, fuel grade, and maintenance. Use combined MPG and annual fuel cost to compare vehicles fairly.
